优化这段代码import requests from bs4 import BeautifulSoup url = "https://www.gupang.com/202305/64619.html" response = requests.get(url) soup = BeautifulSoup(response.content, "html.parser") title = soup.find("h1", class_="title").text content = soup.find("div", class_="content").text print(title) print(content)

可以使用以下方法进行优化：

1. 添加异常处理，以防止请求失败或解析失败导致程序崩溃：

import requests
from bs4 import BeautifulSoup

url = "https://www.gupang.com/202305/64619.html"

try:
    response = requests.get(url)
    response.raise_for_status()  # 抛出异常，如果请求失败
except requests.exceptions.RequestException as e:
    print(e)
    sys.exit(1)

soup = BeautifulSoup(response.content, "html.parser")

try:
    title = soup.find("h1", class_="title").text
    content = soup.find("div", class_="content").text
except AttributeError as e:
    print(e)
    sys.exit(1)

print(title)
print(content)

2. 使用`with`语句来管理资源，以确保在使用完文件或网络连接后自动释放资源：

import requests
from bs4 import BeautifulSoup

url = "https://www.gupang.com/202305/64619.html"

try:
    with requests.get(url) as response:
        response.raise_for_status()
        soup = BeautifulSoup(response.content, "html.parser")
        title = soup.find("h1", class_="title").text
        content = soup.find("div", class_="content").text
except (requests.exceptions.RequestException, AttributeError) as e:
    print(e)
    sys.exit(1)

print(title)
print(content)

这种方法可以避免手动关闭连接或文件，而且代码更加简洁。
